JavaScript используйте метод clearInterval ()

// program to stop the setInterval() method after five times

let count = 0;

// function creation
let interval = setInterval(function(){

    // increasing the count by 1
    count += 1;
    // when count equals to 5, stop the function
    if(count === 5){
        clearInterval(interval);
    }
    // display the current time
    let dateTime= new Date();
    let time = dateTime.toLocaleTimeString();
    console.log(time);

}, 2000);
